Description

Technical Field

[0001] The present application relates to the technical field of washing machines, and in particular to a drum washing machine. Background Art

[0002] Lifting ribs are an important part of the inner drum of the washing machine. They are located on the inner wall of the inner drum of the washing machine. During the washing process, the lifting ribs create friction between the clothes and the lifting ribs. When the part of the clothes close to the lifting ribs rubs against the relatively moving part, a rubbing effect is generated, which helps to remove stains on the clothes. The lifting ribs can also drive the clothes to rotate together. During the rotation process, the clothes are lifted out of the liquid surface and sent to a certain height. Under the action of gravity, the clothes fall back into the detergent.

[0003] The lifting ribs are usually designed as curved strip structures so that the lifting ribs can rub the clothes in multiple directions or angles to improve the washing effect. Although the curved design of the lifting ribs can improve the washing effect, during the washing process, especially in the high-speed spin-drying stage, the lifting ribs in the prior art are easy to squeeze the clothes directly between the inner drum and the door seal, causing damage to the clothes and the door seal.

[0004] In view of this, this application is filed. Utility Model Content

[0069] A first tube opening is provided at the front end of the outer tube 2 , and the first tube opening is arranged opposite to the taking-in and putting-out opening 11 .

[0070] like Figure 4-Figure 6 As shown, the drum washing machine comprises an inner drum 3, which is arranged in an outer drum 2, and the inner drum 3 and the outer drum 2 can rotate relative to each other. The inner drum 3 defines a laundry processing chamber 30, which is used to accommodate laundry.

[0071] It should be noted that the front end of the inner tube 3 is disposed correspondingly to the front end of the outer tube 2 , and the rear end of the inner tube 3 is disposed correspondingly to the rear end of the outer tube 2 .

[0072] The inner drum 3 is provided with a second barrel opening, which is opened at the front end of the inner drum 3, and is connected to the clothing processing chamber 30. The second barrel opening is arranged correspondingly to the taking-in and putting-out opening 11, and the second barrel opening is arranged correspondingly to the first barrel opening, so that the user can take and put clothes into the clothing processing chamber 30 through the taking-in and putting-out opening 11 in sequence through the first barrel opening and the second barrel opening.

[0073] It should be noted that the outer cylinder 2 and the inner cylinder 3 are coaxially arranged inside and outside, so that the inner cylinder 3 can rotate around the axis of the outer cylinder 2.

[0074] The inner drum 3 includes an inner drum peripheral wall 34 and an inner drum side wall 33 . The inner drum side wall 33 is located at the rear end of the inner drum 3 . The inner drum peripheral wall 34 and the inner drum side wall 33 are connected to each other. The peripheral wall and the side wall together define a clothing processing chamber 30 .

[0076] The inner drum 3 is provided with a connecting hole 31 for connecting the inside of the outer drum 2 with the clothing processing chamber 30 , so that water in the outer drum 2 can enter the inner drum 3 through the connecting hole 31 to wash the clothing in the clothing processing chamber 30 .

[0077] In some embodiments, the communication hole 31 is disposed on the circumferential wall 34 of the inner cylinder.

[0078] In some embodiments, the communication hole 31 is disposed on the side wall 33 of the inner cylinder.

[0079] In some embodiments, the communication hole 31 is provided on the inner cylinder peripheral wall 34 and the inner cylinder side wall 33 .

[0080] In some embodiments, a plurality of communicating holes 31 are provided, some of which are provided on the inner cylinder peripheral wall 34 , and some of which are provided on the inner cylinder side wall 33 . The communicating holes 31 provided on the inner cylinder peripheral wall 34 are arranged along the circumferential direction.

[0081] like Figure 2-Figure 6 As shown, the drum washing machine includes lifting ribs 4 , which are arranged on the inner drum peripheral wall 34 , and the lifting ribs 4 are located in the clothing processing chamber 30 .

[0082] When the inner drum 3 rotates relative to the outer drum 2, the lifting ribs 4 can continuously lift the clothes in the clothes processing chamber 30, thereby driving the clothes to be lifted to a certain height and then thrown down, thereby achieving the function of washing the clothes.

[0083] In some embodiments, a plurality of lifting ribs 4 are provided, and the plurality of lifting ribs 4 are circumferentially arranged on the circumferential wall 34 of the inner cylinder.

[0084] When the inner drum 3 rotates relative to the outer drum 2, the plurality of lifting ribs 4 can lift the clothes in the washing chamber in turn, thereby improving the washing effect on the clothes.

[0085] It should be noted that only one lifting rib 4 may be provided, and the number of the lifting ribs 4 may be adjusted as required, which is not limited here.

[0086] In some embodiments, the lifting ribs 4 are detachably fixed to the inner cylinder peripheral wall 34 .

[0087] Specifically, Fig.12 As shown, a first connecting portion 48 is provided on the side of the lifting rib 4 facing the inner cylinder peripheral wall 34 .

[0088] like Figure 5 As shown, the inner tube peripheral wall 34 is provided with a second connection portion 32, and the second connection portion 32 is arranged corresponding to the first connection portion 48. The first connection portion 48 is detachably clamped at the second connection portion 32, so that the lifting rib 4 can be detachably fixed on the inner wall of the inner tube 3.

[0089] In some embodiments, the first connection portion 48 is a buckle, and the second connection portion 32 is a bayonet.

[0090] In some embodiments, a plurality of first connection portions 48 are provided, and the plurality of first connection portions 48 are arranged at intervals on a side of the lifting rib 4 facing the inner wall of the inner tube 3 .

[0091] Correspondingly, there are multiple second connection parts 32 on the inner wall of the inner tube 3, and the multiple first connection parts 48 are arranged in a one-to-one correspondence with the multiple second connection parts 32, that is, the multiple first connection parts 48 can be snap-connected to the multiple second connection parts 32 in a one-to-one correspondence.

[0092] like Figure 6 and Figure 7 As shown, the lifting rib 4 is in the shape of a long strip, one end of the lifting rib 4 in the length direction is arranged toward the loading and unloading port 11, and the other end of the lifting rib 4 in the length direction is arranged toward the inner tube side wall 33, that is, the lifting rib 4 is extended along the front-to-back direction of the inner tube 3.

[0093] The length direction of the lifting rib 4 is substantially arranged along the front-rear direction of the inner tube 3 .

[0094] The side where the lifting rib 4 is connected to the inner tube peripheral wall 34 is the bottom of the lifting rib 4, and the side of the lifting rib 4 away from the connection between the lifting rib 4 and the inner tube peripheral wall 34 is the top of the lifting rib 4. The direction from the top of the lifting rib 4 to the bottom of the lifting rib 4 is the height direction of the lifting rib 4.

[0095] When the inner drum 3 rotates relative to the outer drum 2, the lifting ribs 4 can drive the clothes at the front, middle and rear ends of the clothing processing chamber 30, so that all the clothes in the clothing processing chamber 30 can be lifted and thrown down, thereby effectively ensuring that all the clothes in the clothing processing chamber 30 can be washed.

[0096] like Figure 7 As shown, a ridge 41 is provided on the top of the lifting rib 4 , and the ridge 41 extends along the length direction of the lifting rib 4 .

[0097] In some embodiments, the height of the ridge 41 at one end facing the access opening 11 is different from the height of the ridge 41 at one end facing the inner cylinder side wall 33 .

[0098] In other embodiments, the height of the ridge 41 at one end facing the access opening 11 is smaller than the height of the ridge 41 at one end facing the inner tube side wall 33 .

[0099] like Fig. 9 and Fig.10 As shown, a plane passing through the center of the lifting rib 4 and extending along the length direction of the lifting rib 4 and the height direction of the lifting rib 4 is defined as a reference plane 403.

[0100] One end of the spine 41 close to the access opening 11 is arranged in a direction away from the reference plane 403 along the rotation direction of the inner cylinder 3 , and one end of the spine 41 curve away from the access opening 11 is arranged in a direction opposite to the rotation direction of the inner cylinder 3 and away from the reference plane 403 .

[0101] It should be noted that when the inner drum 3 runs at high speed to wash or dry the clothes in the clothes processing chamber 30 , the end of the spine 41 close to the loading and unloading port 11 pushes the clothes toward the inner drum side wall 33 to move the clothes toward the inner drum 3 .

[0102] By taking the plane passing through the center of the lifting rib 4 and extending along the height and length directions of the lifting rib 4 as the reference plane 403, the end of the spine 41 of the lifting rib 4 facing the loading and unloading port 11 is bent along the rotation direction of the inner drum 3 in a direction away from the reference plane 403, and the end of the spine 41 of the lifting rib 4 away from the loading and unloading port 11 is bent in a direction opposite to the rotation direction of the inner drum 3 in a direction away from the reference plane 403, so that the end of the lifting rib 4 facing the loading and unloading port 11 can push the clothes toward the inner drum 3, thereby preventing the clothes from being squeezed between the inner drum 3 and the door seal due to moving toward the loading and unloading port, causing damage to the clothes and the door seal.

[0103] The spine 41 includes a first curved portion 411 . The first curved portion 411 is disposed close to the access opening 11 . The first curved portion 411 is curved along the rotation direction of the inner cylinder 3 toward a direction away from the reference plane 403 .

[0104] By bending the first curved portion 411 along the rotation direction of the inner drum 3 away from the reference plane 403 , the end of the spine 41 facing the access opening 11 is pushed toward the inner drum side wall 33 , so that the clothes move toward the inner drum 3 .

[0105] The spine 41 includes a second curved portion 412, which is arranged away from the access port 11. The second curved portion 412 and the first curved portion 411 are arranged along the length direction of the lifting rib 4, and the second curved portion 412 is bent in a direction opposite to the rotation direction of the inner tube 3 toward a direction away from the reference plane 403.

[0106] like Fig.10 and Fig.11 As shown, a first boundary line 401 is defined at a connection between the lifting rib 4 and the inner tube peripheral wall 34 , and the first boundary line 401 extends along the length direction of the lifting rib 4 .

[0107] The first boundary line 401 defines a first reference line 405 at both ends along the length direction of the lifting rib 4 . The first reference line 405 and the reference plane 403 are arranged in sequence along the rotation direction of the inner cylinder 3 .

[0108] In some embodiments, a middle portion of the first boundary line 401 is bent toward the reference plane 403 .

[0109] The connection between the lifting rib 4 and the inner cylinder peripheral wall 34 defines a second boundary line 402, and the second boundary line 402 extends along the length direction of the lifting rib 4. The first boundary line 401 and the second boundary line 402 are arranged along the rotation direction of the inner cylinder 3.

[0110] The second boundary line 402 defines a second reference line 406 at both ends along the length direction of the lifting rib 4 , and the second reference line 406 and the reference plane 403 are arranged in sequence along the rotation direction of the inner cylinder 3 .

[0111] In some embodiments, a middle portion of the second boundary line 402 is bent toward the reference plane 403 .

[0112] In some embodiments, the first boundary line 401 and the second boundary line 402 are symmetrically arranged with respect to the reference plane 403 .

[0113] The distance between the first boundary line 401 and the end of the spine 41 facing the access port 11 is D1, and the distance between the first boundary line 401 and the end of the spine 41 away from the access port 11 is d1. D1 and d1 satisfy the relationship: D1 <d1。

[0114] The distance between the second boundary line 402 and the end of the spine 41 facing the access opening 11 is D2, and the distance between the second boundary line 402 and the end of the spine 41 away from the access opening 11 is d2. D2 and d2 satisfy the relationship: D2>d2.

[0115] In some embodiments, a distance D1 between the first boundary line 401 and the end of the spine 41 facing the access port 11 and a distance D2 between the second boundary line 402 and the end of the spine 41 facing the access port 11 satisfy the relationship: D2>D1.

[0116] In some embodiments, the distance d1 between the first boundary line 401 and the end of the spine 41 away from the access opening 11 and the distance d2 between the second boundary line 402 and the end of the spine 41 away from the access opening 11 satisfy the relationship: d1>d2.

[0117] In some embodiments, the spine 41 is arranged in an S shape from one end of the spine 41 close to the loading and unloading port 11 to one end of the spine 41 close to the inner cylinder side wall 33 .

[0118] The lifting rib 4 defines a first center line 404 , which passes through the center of the lifting rib 4 and intersects with the reference plane 403 .

[0119] In some embodiments, the first center line 404 is arranged correspondingly along the rotation direction of the inner cylinder 3 .

[0120] The intersection of the first center line 404 and the reference plane 403 is point A, and point A is disposed away from the spine 41 .

[0121] In some embodiments, point A is disposed away from the spine 41 along the rotation direction of the inner container.

[0122] In some embodiments, the first boundary line 401 is symmetrically arranged about the first center line 404 .

[0123] In some embodiments, the second boundary line 402 is symmetrically disposed about the first center line 404 .

[0124] like Figure 7 As shown, the lifting rib 4 includes a first curved surface 42 , and the first curved surface 42 is located on a side of the lifting rib 4 corresponding to the rotation direction of the inner cylinder 3 .

[0125] The distance between the first curved surface 42 and the first boundary line 401 gradually decreases from the side where the first curved surface 42 is connected to the inner cylinder peripheral wall 34 to the side where the first curved surface 42 is away from the inner cylinder peripheral wall 34 .

[0126] That is, the distance between the first curved surface 42 and the first boundary line 401 gradually decreases along the height direction of the lifting rib 4 .

[0127] The lifting rib 4 includes a restraining portion 421 , which is located on the first curved surface 42 and is disposed close to the taking-in and putting-out opening 11 . The restraining portion 421 is used to push the clothes toward the inner drum 3 .

[0128] When the drum washing machine runs at high speed to wash or dry clothes, the restraining part 421 applies a force to the clothes that is inclined toward the inner drum side wall 33 along the rotation direction of the inner drum 3, so that the clothes are pushed toward the inner drum side wall 33 to prevent the clothes from moving toward the loading and unloading port 11.

[0129] The lifting rib 4 includes a second curved surface 43, which is arranged corresponding to the first curved surface 42. The side of the second curved surface 43 away from the inner tube peripheral wall 34 and the side of the first curved surface 42 away from the inner tube peripheral wall 34 together define a ridge 41.

[0130] In some embodiments, the second curved surface 43 may be provided with a constraint portion 421 . When the constraint portion 421 is provided on the second curved surface 43 , the constraint portion 421 is provided close to the inner cylinder side wall 33 .

[0131] The distance between the second curved surface 43 and the first boundary line 401 gradually decreases from the side where the second curved surface 43 is connected to the inner cylinder peripheral wall 34 to the side where the second curved surface 43 is away from the inner cylinder peripheral wall 34 .

[0132] That is, the distance between the second curved surface 43 and the first boundary line 401 gradually decreases along the height direction of the lifting rib 4 .

[0133] The lifting rib 4 defines an accommodating cavity 46 inside which an anti-scaling module is provided. The anti-scaling module is provided with an anti-scaling agent. The anti-scaling module is used to pre-treat the water entering the outer drum 2 from the water inlet valve so that the washing water entering the outer drum 2 can undergo a chelating reaction with the anti-scaling agent in the anti-scaling module, thereby making it difficult for the washing water to form scale when heated, which is beneficial to increasing the service life of the heating tube and improving the quality of washed clothes.

[0134] The lifting rib 4 includes a water inlet portion 422 . The water inlet portion 422 is disposed on the first curved surface 42 . The water inlet portion 422 is disposed close to the inner tube side wall 33 .

[0135] The water inlet portion 422 is provided with a water inlet hole 44 , which is in communication with the accommodating chamber 46 . The water inlet hole 44 is used to connect the accommodating chamber 46 and the laundry processing chamber 30 .

[0136] The washing liquid in the laundry processing chamber 30 can enter the accommodating chamber 46 through the water inlet hole 44 , or the washing liquid in the accommodating chamber 46 can enter the laundry processing chamber 30 through the water inlet hole 44 .

[0137] In some embodiments, a plurality of water inlet holes 44 are provided, and the plurality of water inlet holes 44 are located on the side wall of the lifting rib 4 facing the clothing processing chamber 30 .

[0138] It should be noted that the number and density of the water inlet holes 44 can be adjusted as needed and are not limited here.

[0139] The distance between the constraint portion 421 disposed on the first curved surface 42 and the first boundary line 401 is usually smaller than the distance between the water inlet portion 422 disposed on the first curved surface 42 and the first boundary line 401 .

[0140] In some embodiments, the second curved surface 43 is provided with a water inlet 422 . When the water inlet 422 is provided on the second curved surface 43 , the water inlet 422 is provided close to the loading and unloading port 11 .

[0141] The distance between the constraint portion 421 disposed on the second curved surface 43 and the first boundary line 401 is usually smaller than the distance between the water inlet portion 422 disposed on the second curved surface 43 and the first boundary line 401 .

[0142] like Fig.12 As shown, a partition 47 is provided in the lifting rib 4 , and the partition 47 is used to separate the space of the accommodating cavity 46 .

[0143] In some embodiments, the first connection portion 48 and the partition 47 are integrally formed, and the first connection portion 48 protrudes and extends from the partition 47 toward the inner wall of the inner tube 3, thereby improving the structural strength of the first connection portion 48 and the partition 47.

[0144] In some embodiments, a plurality of partitions 47 are provided, and the plurality of partitions 47 are arranged at intervals, thereby dividing the accommodating cavity 46 into a plurality of chambers.

[0145] In some embodiments, a plurality of anti-scaling modules are provided, and the plurality of anti-scaling modules are respectively arranged in different chambers. Therefore, the washing water entering different chambers can enter the anti-scaling modules in the corresponding chambers.

[0146] In some embodiments, an opening is formed on one side of the lifting rib 4 facing the inner wall of the inner tube 3. When the first connection portion 48 of the lifting rib 4 is buckled with the second connection portion 32 on the inner wall of the inner tube 3, the peripheral edge of the opening of the lifting rib 4 can be attached to the inner wall of the inner tube 3, thereby forming a receiving cavity 46 between the lifting rib 4 and the inner wall of the inner tube 3.

[0147] In some embodiments, the second connection portion 32 can connect the accommodating chamber 46 and the external space of the inner drum 3, and the washing water between the outside of the inner drum 3 and the inside of the outer drum 2 can enter the accommodating chamber 46 through the second connection portion 32, thereby allowing the water in the area between the outer wall of the inner drum 3 and the inner wall of the outer drum 2 to enter the clothing processing chamber 30 through the second connection portion 32, the accommodating chamber 46, and the water inlet hole 44, or the washing liquid in the clothing processing chamber 30 can also enter the area between the outer wall of the inner drum 3 and the inner wall of the outer drum 2 through the water inlet hole 44, the accommodating chamber 46, and the second connection portion 32 in sequence.

[0148] The lifting rib 4 includes two side surfaces 45, and the two side surfaces 45 are respectively located at two ends of the length direction of the lifting rib 4. It should be noted that the first curved surface 42, the second curved surface 43 and the two side surfaces 45 define a receiving cavity 46 together.

[0149] In some embodiments, the side surface 45 located at the end of the lifting rib 4 facing the clothing access opening 11 is inclined toward the first center line 404 along the height direction of the lifting rib 4 .

[0150] In some embodiments, the side surface 45 located at the end of the lifting rib 4 away from the clothing access opening 11 is inclined toward the first center line 404 along the height direction of the lifting rib 4 .

[0151] In some embodiments, the side surface 45 at the end of the lifting rib 4 facing the clothing access opening 11 and the side surface 45 at the end of the lifting rib 4 away from the clothing access opening 11 are symmetrically arranged about the first center line 404 .

[0152] It should be noted that, in this embodiment, the height of the lifting ribs 4 is smaller than that of the lifting ribs 4 in the prior art, thereby reducing the space occupied by the lifting ribs 4 inside the inner drum 3, thereby increasing the movement space for clothes during washing while ensuring the washing effect.

[0153] The working principle of the above-mentioned drum washing machine is as follows: when clothes need to be washed, the clothes are placed in the clothes processing chamber 30 from the loading and unloading port 11 through the first barrel opening and the second barrel opening, the cabinet door 12 is closed, and the inner barrel 3 and the outer barrel 2 are rotated relative to each other through the control system, the power supply system, and the driving system. The clothes in the clothes processing chamber 30 rotate with the inner barrel 3, and the clothes are raised to a certain height under the action of the lifting ribs 4 and then thrown down. The constraint part 421 located on the first curved surface 42 makes the clothes move toward the side wall of the inner barrel 3 to prevent the clothes from moving to the second barrel opening and contacting the door seal to cause damage to the clothes.

[0154] The drum washing machine can not only effectively ensure that all clothes in the clothes processing chamber 30 can be washed clean, but also prevent the clothes from contacting the door seal, thereby avoiding damage to the clothes due to interaction with the door seal.

[0155] It should be noted that the control system, power system, drive system, etc. required for the operation of the drum washing machine belong to conventional technical means in the field and will not be elaborated herein.

[0156] The above-mentioned drum washing machine uses a plane passing through the center of the lifting rib 4 and extending along the height and length directions of the lifting rib 4 as a reference plane 403, bends one end of the back 41 of the lifting rib 4 toward the loading and unloading port 11 along the rotation direction of the inner drum 3 in a direction away from the reference plane 403, and bends one end of the back 41 of the lifting rib 4 away from the loading and unloading port 11 in a direction opposite to the rotation direction of the inner drum 3 in a direction away from the reference plane 403, so that the end of the lifting rib 4 toward the loading and unloading port 11 can push the clothes toward the inner drum 3, thereby preventing the clothes from being squeezed between the inner drum 3 and the door seal due to moving toward the loading and unloading port, causing damage to the clothes and the door seal.
